直拉SiGe合金的高温Seebeck系数
Seebeck Coefficient of Czochralski SiGe Alloy at High Temperatures
摘要
Abstract
To investigate the possibility of improvement in the thermoelectric properties of SiGe alloys, we examined several different silicon-germanium alloys with different contents,orientations,and electric conductive types. The thermoelectric properties of single crystal SiGe alloy were compared with those of poly-crystals. Experiment results show that the Seebeck coefficient of the sample depends on the temperature. All the samples show a maximal Seebeck coefficient in the temperature range of 700~900K. The Seebeck coefficient of the sample with (111) orientation is smaller than that of the sample with <100> orientation at the same temperature. The Seebeck coefficient of the SiGe alloy also depends on Ge content.关键词
